IMPROVEMENT IN CALF-MUZZLES.

Specification forming part of Letters Patent No. 199,156, dated January1 5, 1878 application filed April 14, 1877.

To all whom 'it 'may concern Be it known that I, ROBERT S. HAZEN, Sr.,of Oalmus, in the county of Clinton and State of Iowa, have inventedcertain Improvements in Oalf-Muzzles, of which the following is aspecification My invention consists in a muzzle provided with inside andoutside barbs, so arranged and connected that a pressure upon theoutside barbs causes those on the inside to enter the nose of the calf,and in other details hereinafter described.

Figure l represents a perspective view of my muzzle; Fig. 2, a verticalcross-section of the same; Fig. 3, a face view of a modified form of themuzzle.

A represents a flat metal plate, in the center of which a tongue, a, ispunched loose on three of its sides, and bent outward out of line withthe plate. On the outside of the tongue a there are two barbs or spurs,c, eX-

tending outward, as shown, and at the upper free edge ofthe tongue thereare two spurs or barbs, b,.eXtending inward on the side which is appliednext to the calfs muzzle when the deviceis in use. Under ordinarycircumstances the tongue a stands outward in the manner shown, with thepoints of the barbs or spurs b ilush with or outside of the face of theplate A, which latter serves as a guard to prevent them from enteringthe nose of the calf.

B represents a bent spring, attached to the upper edge of the plate A byrings d, and provided at its ends. with rubber balls c to enter thenostrils of the calf and sust-ain the plate in front of the nose.

So long as the calf makes no effort to milk the mother cow the muzzle ispainless in its action, and causes no inconvenience; but the4 punishesboth the cow and the calf at the same time, I find very efficient; andas it quickly teaches the calf that every attempt to milk the cow isfollowed by pain, the calf soon learns to keep away, and consequentlythe cow is spared the torture consequent upon the use of the ordinarymuzzles, which cause the calf no pain, and with which the calfconstantly and violently assals the cow.

Having described my invention, what I claim is l. The calf-muzzleconsisting of the plate A, provided with the suspending device B andwith the spring-tongue a, having the inner barbs b and outer barbs c.

2. In a calf -muzzle, inwardly-projecting barbs or spurs, in combinationwith a spring to hold them out of contact with the nose of the animalunless outward pressure is applied, substantially as shown and setforth.
